Description

[0001]
[Technical field to which the invention belongs]
The present invention relates to a coin sorting device that mechanically sorts coins such as coins, tokens, medals, or substitute coins into genuine coins and fake coins.
In particular, the present invention relates to an improvement of a coin sorting device used for a game machine such as a pachislot machine.
The “coin” used in this specification includes a currency, a coin, a medal, a substitute coin, and the like.
[0002]
[Prior art]
A coin sorting device used in a conventional game machine is provided with an insertion slot, a guide rail, a fixed gauge part, a cancel piece, an exit, and a coin counting sensor. For example, see Japanese Patent No. 2742755.
In this prior art, the guide rail and the fixed gauge portion are set at a predetermined interval, and a coin inclined with respect to the coin surface rolls on the guide rail while its upper end side surface is supported by the fixed gauge.
In addition, there is known a cancel piece that protrudes from the guide rail to a position substantially away from the radius of the coin with respect to the coin rolling on the guide rail (see JP 2000-348231).
[0003]
In the former case, when a coin slightly smaller than the gauge part rolls while bouncing, there is a concern that the coin is guided and not separated by the fixed gauge part when bound.
In order to reduce this concern, when the coin size is changed, it is necessary to accurately adjust the gauge portion.
In the latter case, when the coin bounces, there is a concern that it will get over the cancel piece and will not be separated.
[0004]
[Problems to be solved by the invention]
A first object of the present invention is to improve coin sorting accuracy.
A second object of the present invention is to make it unnecessary to change the operation timing of the cancel unit when the size of the coin is changed.
[0005]
[Means for Solving the Problems]
In order to achieve this object, the invention of claim 1 is configured as follows.
coin (14) Coin passage that rolls (108) Forming guide rail (twenty two) And a coin sorting window formed along the guide rail ( 116 ) And the guide rail (twenty two) Coins on the guide rail extending in parallel with a predetermined interval above (14) To support the rolling of the upper end side of the window ( 116 ) And a coin that rolls on the guide rail and is positioned above the side surface of the upper end portion of the coin. 116 ) And a cancel piece that can be moved to a cancel position where the coin falls from the guide rail. 82 )When,
The cancellation piece ( 82 ) And the coin passage when the cancel piece is in the non-cancel position. (108) The coin passage when the cancel piece is in the cancel position (108) Stopper that protrudes inward and prevents coins from rolling 28 ) Is a coin canceling device of the coin sorting device.
[0006]
In this configuration, when the coin is not accepted, the gauge device and the stopper are moved to the cancel position.
For this reason, since the gauge device for determining the authenticity of the coin does not guide the authentic coin, the coin rolling on the guide rail is lost in balance and dropped from the guide rail and canceled.
Even if it passes through the gauge device in rare cases, it collides with a stopper located farther from the guide rail than the coin radius in the coin path, and the balance is lost to fall from the guide rail.
At the time of the collision, since the stopper contacts the upward circumferential surface of the coin, the coin is pressed downward and pressed against the guide rail.
In other words, the coin never gets over the stopper.
As a result, the coin is reliably canceled.
[0007]
Further, when the coin is canceled, the coin falls without being supported by the gauge device and falls to the side of the guide rail and falls, so that the following coin is not placed on the coin in the middle of dropping and guided to the exit.
In other words, there is no “smearing” in which a coin to be canceled is accepted.
[0008]
Preferably, a coin sensor is disposed downstream of the stopper, and the gauge device and the stopper are moved from the non-cancel position to the cancel position based on a detection signal of the coin sensor.
[0009]
In this configuration, the gauge device and the stopper are moved from the non-cancel position to the cancel position based on the detection signal of the coin sensor disposed downstream of the stopper.
In other words, the gauge device and the stopper are moved to the cancel position in order to cancel the next coin based on the detection signal of the coin that has passed through the gauge device.
Therefore, since a sufficient time can be taken for the operation of the moving device, a sufficient time can be secured even if an inexpensive solenoid is used, so that it can be configured at a low cost.
[0010]
According to a third aspect of the present invention, there is provided a guide rail for guiding a coin from an insertion slot to an outlet, a large-diameter gauge disposed in parallel with the guide rail at a predetermined interval, and the guide rail on a side of the large-diameter gauge. A small-diameter gauge capable of pivoting about a pivot disposed in parallel, a stop piece for holding the small-diameter gauge in a non-cancellation position, a moving device for moving the small-diameter gauge to a non-cancel position and a cancel position, and the small diameter Coin sorting including a stopper that is movable in conjunction with the small-diameter gauge to a cancel position farther from the guide rail than the radius of the coin in the coin passage from the lever extending from the gauge to the guide rail side and a non-cancel position outside the coin passage. It is a coin cancellation device of the device.
[0011]
In this configuration, when the coin has a diameter larger than that of the genuine coin, the coin is canceled by the large diameter gauge.
Further, in the case of a coin having a smaller diameter than the genuine coin, it is not guided by the small diameter gauge, so it falls from the guide rail and is canceled.
At this time, since the position of the small-diameter gauge is held by the stop piece, the selection is performed stably.
[0012]
In the case of a genuine coin, the coin tilts and rolls on the guide rail, and the side surface of the upper end is guided and received by a small-diameter gauge.
When canceling the genuine coin, the small-diameter gauge pivots about the pivot and moves to the cancel position, and the integral stopper moves from the non-cancel position to the cancel position.
Thereby, since the genuine coin is not supported by the small diameter guide, it falls in the middle of the guide rail, and when it does not fall, it is finally stopped by the stopper and canceled.
At this time, since the stopper contacts the upper side of the radius of the genuine coin, the genuine coin receives a force toward the guide rail and is reliably canceled without getting over the stopper.
[0013]
According to a fourth aspect of the present invention, there is provided a guide rail that forms a coin passage through which coins roll, a gauge device that selects coins that roll on the guide rail, and a guide that is arranged downstream of the gauge device and that is less than the radius of the coin in the coin passage. A stopper that can be moved to a cancel position far from the rail and a non-cancel position outside the coin passage, the gauge device and a stopper that moves to the cancel position and the non-cancel position, and a coin passage that is downstream of the stopper. And a cancel circuit for demagnetizing the solenoid based on coin detection by the sensor and moving the stopper to the cancel position.
[0014]
In this structure, the stopper is moved to the cancel position by a solenoid that is operated based on detection by a sensor disposed downstream of the stopper.
In other words, the coin that rolls following the coin detected by the sensor is stopped by the stopper and canceled.
In this case, since the stopper is moved based on the detection by the sensor of the previous coin, even when the next coin is connected, it can be set to enter between the previous coin and the next coin.
Therefore, even if coins are consecutive, it is possible to cancel the coins with certainty.

[0016]
As shown in FIG. 1, the coin sorting device 10 sorts the coins 14 inserted into the insertion slot 12 by the gauge device 16, discharges the genuine coins from the outlet 18, and removes the false coins and the unacceptable genuine coins from the cancel unit 20. Discharge.
The coin sorting device 10 according to the present invention includes a guide rail 22, a gauge device 16 (large diameter gauge 24, small diameter gauge 26), a stopper 28, and a stopper 28 moving device 30 (see FIG. 4).
[0017]
The guide rail 22 is formed on the base 32 and has a function of guiding the coin 14.
The base 32 has a left end attachment portion 34 and a right end attachment portion 36 fixed to a vertical wall (not shown) of the game machine.
As shown in FIG. 1, the base 32 has an inverted J shape and is integrally formed of a wear-resistant resin.
A coin guide surface 44 including a vertical surface 38, a curved surface 40 and an inclined surface 42 is formed on the base 32.
[0018]
The vertical surface 38 extends in the vertical direction.
As shown in FIGS. 5 and 6, the inclined surface 42 is inclined about 70 degrees with respect to the horizontal line.
That is, the coin 14 rolls on the guide rail 22 with the front and back surfaces thereof being inclined.
The curved surface 40 connects the vertical surface 38 and the inclined surface 42 with a gentle curve, and is inclined about 70 degrees with respect to the horizontal line in the same manner as the inclined surface 42.
[0019]
The lower end of the vertical surface 38 and the upper end of the curved surface 40 are connected by a smooth curved surface.
The coin guide surface 44 only needs to have a function of guiding the coin 14 from the insertion slot 12 to the outlet 18.
Therefore, in order to reduce the frictional resistance against the coin 14, it is possible to form a groove or a protrusion extending in the traveling direction on the coin guide surface 44.
[0020]
Next, the structure of the guide rail 22 will be described.
The guide rail 22 forms a right angle with respect to the coin guide surface 44 and has a width slightly larger than the thickness of the coin 14 in most part.
The guide rail 22 includes a vertical guide rail 45, an arcuate guide rail 46, and an inclined guide rail 48.
[0021]
The inclined guide rail 48 is positioned relative to the inclined surface 42, is formed integrally with the base 32, and is inclined downward to the right in FIG. 1, so that the coin 14 can roll down by gravity.
The arc-shaped guide rail 46 has a crescent shape having an arc-shaped guide surface 50, is made of a metal such as stainless steel, and is fixed to the base 32 by a screw 52 so as to be opposed to the curved surface 40.
The reason why the arc-shaped guide rail 46 is made of metal is to prevent the arc-shaped guide surface 50 from being subjected to centrifugal force in addition to the weight of the coin 14 and thus preventing wear due to an increase in the contact pressure of the coin 14.
The arcuate guide surface 50 is substantially continuous with the inclined guide rail 48.
[0022]
The vertical guide rail 45 is formed integrally with the base 32, is positioned relative to the vertical surface 38, and is substantially continuous with the arcuate guide surface 50.
The arcuate guide rail 46 may be formed of resin integrally with the inclined guide rail 48 and the vertical guide rail 45.
In this case, it is necessary to affix a wear prevention plate made of a material having wear resistance such as a metal plate to at least the arcuate guide surface 50 of the arcuate guide rail 46.
When the metal arcuate guide rail 46 is used, it is less expensive than using a resin having wear resistance.
[0023]
After the coin 14 falls along the vertical guide rail 45, it is guided by the arcuate guide surface 50 of the arcuate guide rail 46 to change the direction, and after moving to the inclined guide rail 48, it rolls on it and reaches the outlet 18. .
Note that a groove may be formed in the longitudinal direction of the guide rail 22 in order to prevent coin rolling failure due to dust adhesion.
[0024]
Next, the cover 54 will be described with reference to FIG.
The cover 54 is positioned relative to the vertical surface 38, the curved surface 40, and the inclined surface 42, and has a function of guiding the coin 14.
A cover vertical surface 56, a cover curved surface 58, a cover inclined surface 60, and a cover vertical guide 62 are formed on the cover 54 so as to be opposed to the vertical surface 38, the curved surface 40, and the inclined surface 42.
The cover 54 is attached so as to be pivotable integrally with the extrusion piece 66 by inserting the U-shaped insertion portion 64 at the upper end thereof into the insertion port 68 (see FIG. 2) above the extrusion piece 66.
As shown in FIG. 1, the extruded piece 66 is pivotally attached to a bearing 70 above the inclined surface 42 of the base 32.
[0025]
As shown in FIG. 3, the cover vertical surface 56 and the cover curved surface 58 are formed with a first guide surface 72 and a second guide surface 74 having different distances from the vertical surface 38 and the curved surface 40, respectively.
The first guide surface 72 is J-shaped and is formed along the vertical guide rail 45 and the curved guide rail 46, and the distance between the vertical surface 38 and the curved surface 40 is slightly larger than the thickness of the coin 14.
The second guide surface 74 is linear and is formed at a position far from the vertical guide rail 45 and the arcuate guide rail 46, and is disposed at a position farther from the first guide surface 72 with respect to the vertical surface 38 and the curved surface 40. Is done.
As shown in FIG. 5, the extruded piece 66 has a transverse V shape in cross section.
[0026]
As shown in FIG. 5, by the compression spring 76 disposed between the upper end portion of the extruded piece 66 and the base 32, the extruded piece 66 and the cover 54 are given a rotational force in the counterclockwise direction, and the cover 54 is attached to the base 32. To approach.
The distance between the cover 54 and the base 32, that is, the distance between the vertical surface 38 and the cover vertical surface 56, the curved surface 40 and the cover curved surface 58, and the inclined surface 42 and the cover inclined surface 60 is the screw 78 ( 2) is set so as to be slightly wider than the thickness of the coin 14 by abutting against the screw 52 on the side surface of the arc-shaped guide rail 46.
[0027]
Next, the gauge device 16 will be described.
The gauge device 16 has a function of selecting genuine coins and fake coins based on the coin diameter.
The gauge device 16 includes a substantially trapezoidal gauge plate 80 and a cancel piece 82, as shown in FIGS.
A guide surface 84 of the coin 14 is formed on a part of the end surface of the gauge plate 80.
The guide surface 84 is formed with a vertical guide 86 on the left side and an inclined guide 88 on the lower surface, and a curved guide 90 connecting the vertical guide 86 and the inclined guide 88.
[0028]
The vertical guide 86 extending in the vertical direction is opposed to the vertical guide rail 45 and the cover vertical guide 62 and is slightly separated from the diameter of the coin 14.
The curved guide 90 is opposed to the arcuate guide rail 46 and is slightly separated from the diameter of the coin 14.
The inclined guide 88 extending in an inclined manner is arranged in parallel to the inclined guide rail 48 and in parallel.
[0029]
The distance between the inclined guide rail 48 and the inclined guide 88 is slightly separated from the diameter of the coin 14 so that the genuine coin 14 can pass smoothly.
This separated distance is the maximum allowable diameter of the coin 14 at that position of the gauge plate 80.
That is, the inclined guide 88 also serves as the large diameter gauge 24.
In the present embodiment, the maximum allowable diameter is set at the position of the gauge plate 80 adapted to the small diameter coin and the position of the gauge plate 80 adapted to the large diameter coin.
[0030]
Next, the attachment device 92 for the gauge plate 80 will be described with reference to FIG.
The gauge plate 80 is attached to the upper side surface of the base 32 by an attachment device 92.
The attachment device 92 includes an attachment portion 94 of the base 32 and an attachment portion 95 of the gauge plate 80.
The gauge plate 80 is detachably attached to the base 32 with one touch by fitting a hole-like gauge attaching portion 95 to the pin-like base attaching portion 94.
[0031]
Although the base mounting portions 94 are arranged in a pair on the left and right sides, they have the same structure, so that the right side device in FIG. 2 will be described as a representative.
In the base mounting portion 94, a first holding pin 96 having a conical tip and a columnar base is fixed to the base 32.
Similarly formed second holding pins 98 are arranged at predetermined intervals on a straight line L inclined by 45 degrees with respect to the inclined guide rail 48 (see FIG. 1).
[0032]
The gauge mounting portion 95 is opposed to the first holding pin 96 and the second holding pin 98, and the first fitting hole 100 and the second fitting hole 102 formed in the gauge plate 80 and the third fitting pin arranged on the same line. The fitting hole 104 and the holding body 106 are included.
The first to third fitting holes 100, 102, and 104 are formed to have diameters that closely fit the cylindrical portions of the first holding pin 96 and the second holding pin 98.
[0033]
The holding body 106 is formed in a cantilever state integrally with the gauge plate 80.
The tip of the holding body 106 comes into contact with the peripheral surface of the first holding pin 96 or the second holding pin 98 inserted into the second fitting hole 102 and is pressed by its elasticity to hold the position of the gauge plate 80.
Further, a hook (not shown) formed on the side surface of the holding body 106 is hooked into a groove (not shown) formed on the side surface of the first holding pin 96 and the second holding pin 98 to prevent the gauge plate 80 from falling off. To do.
[0034]
The holding body 106 only needs to have a function of holding the gauge plate 80 on the pins 96 and 98, and other structures can be adopted.
As shown in FIG. 1, when the first holding pin 96 is fitted in the first fitting hole 100 and the second holding pin 98 is fitted in the second fitting hole 102, the distance between the gauge plate 80 and the guide rail 22 is reduced. Therefore, it is located at the sorting position for small-diameter coins.
[0035]
When the first holding pin 96 is fitted into the second fitting hole 102 and the second holding pin 98 is fitted into the third fitting hole 104, the distance between the gauge plate 80 and the guide rail 22 is increased. Located at the sorting position.
That is, the gauge plate 80 approaches or leaves the vertical guide rail 45, the arcuate guide rail 46 and the inclined guide rail 48 along the straight line L by the same distance.
[0036]
Therefore, when the position of the gauge plate 80 is changed, the width of the coin passage 108 (in the coin diameter direction) is adjusted to be the same in all of the vertical portion passage 110, the curved portion passage 112, and the inclined portion passage 114.
The attachment device 92 can be changed to another mechanism having a function of attaching the gauge plate 80 to the base 32.
[0037]
Furthermore, the attachment device 92 preferably has a function of changing the position of the gauge plate 80 so as to match the diameter of the coin to be selected.
Therefore, the attachment device 92 can be configured so that the position of the gauge plate 80 can be adjusted in three or more stages or in a stepless manner.
[0038]
Next, the coin passage 108 will be described with reference to FIG.
The coin passage 108 is a passage surrounded by the coin guide surface 44 of the base 32, the cover guide surface 31 of the cover 54, the guide rail 22, and the guide surface 84 of the gauge plate 80.
The coin passage 108 has an inverted J shape in FIG. 1 and includes a vertical portion passage 110, a curved portion passage 112, and a downwardly inclined slope passage 114 extending almost directly from the insertion slot 12.
[0039]
Next, the cancel piece 82 will be described.
The cancel piece 82 is arranged facing the inclined passage 114.
A rectangular window 116 is formed on the inclined surface 42 along the inclined guide rail 48 and the inclined guide 88.
As shown in FIG. 3, bearings 118 and 120 are fixed to both sides of the window 116 on the back surface of the base 32.
As shown in FIG. 5, the bearings 118 and 120 are respectively formed with a large-diameter bearing groove 122 and a small-diameter bearing groove 124 that extend in a direction perpendicular to the inclined surface 42.
[0040]
As shown in FIG. 8, the cancel piece 82 has a plate shape, and columnar pivots 126 are formed at both ends.
The pivot 126 is disposed parallel to the inclined guide rail 48 and the inclined guide 88 and beside the large-diameter gauge 24 as shown in FIG.
Here, the horizontal is a direction orthogonal to a plane including the coin passage 108.
The tip 128 of the cancel piece 82 is formed in an arc centered on the pivot 126.
Even if the position of the cancel piece 82 is adjusted by the fine adjustment device 130 (FIG. 6) by this arc, the tip 128 is the same distance from the pivot 126, so that the genuine coin 14 can be guided in the same posture.
[0041]
The pivot shaft 126 is inserted into the small-diameter bearing groove 124 and is held by a pressing plate (not shown) so as to be pivotable.
Thereby, the pivot 126 is arranged in parallel with the inclined guide rail 48 and the inclined guide 88 which is the large diameter gauge 24.
The tip 128 of the cancel piece 82 is disposed in the window 116 near the inclined guide 88 in a plane including the inclined surface 42.
[0042]
The position of the lower edge 132 of the tip 128 is arranged away from the inclined guide rail 48 by the diameter of the smallest coin that accepts, in other words, the diameter of the small coin that does not accept.
This position is the non-cancellation position 133 of the small diameter gauge 26 (cancellation piece 82).
Therefore, the tip 128 of the cancel piece 82 is disposed adjacent to the side of the gauge plate 80.
[0043]
When the genuine coin 14 rolls on the inclined guide rail 48, the inclined passage 114 is inclined to the right side as shown in FIG. 5, and accordingly, the lower end side surface is supported by the inclined surface 42, and The side surface of the upper end can be supported by the tip 128 of the cancel piece 82 and reach the outlet 18.
When the diameter of the coin 14 is a small diameter that does not allow acceptance, the side surface of the upper end portion is not supported by the tip 128, so that it falls into the window 116 by its own weight as shown by a one-dot chain line in FIG.
[0044]
As a result, the coin 14 is detached from the inclined guide rail 48 and falls at the cancel unit 20.
That is, the cancel piece 82 is the small diameter gauge 26.
The cancel piece 82 only needs to have a function of removing the genuine coin 14 from the inclined guide rail 48.
[0045]
As shown in FIG. 7, from the downstream end of the coin of the cancel piece 82lever 180 ButA stopper 28 protrudes downward from the middle toward the inclined passage 114.
When the stopper 28 enters the inclined passage 114, the stopper 28 advances and retreats to a position farther from the inclined guide rail 48 than the center of the coin 14.
  In other words, when the cancel piece 82 is moved to the cancel position 135 (the chain line position in FIG. 5), the stopper 28 moves to the inclined passage 114 and is positioned at the cancel position 143 to force the coin 14 to roll. Stop and drop from the inclined guide rail 48 to cancel.
[0046]
Further, when the cancel piece 82 is in the non-cancel position 133 in the normal state, the stopper 28 is located in the non-cancel position 145 with the tip end being located in the window 116 and retracted from the inclined passage 114.
In the stopper 28, a downward surface 139 following the lower side of the upstream side surface 137 is inclined with respect to the inclined guide rail 48.
In other words, when the coin 14 collides with the downward surface 139, the coin 14 moves from the inclined guide rail 48 without getting over the stopper 28 so as to generate a reaction force downward with respect to the coin 14 and thus toward the inclined guide rail 48. It is supposed to fall.
[0047]
  The downstream side surface 141 is substantially orthogonal to the inclined passage 114.
  If you will see later1st coin sensor 164 TheWhen the coin is to be returned by the connected thread after passing through, the coin 14 has a stopper because the upward arc surface of the coin is locked to the lower edge of the downstream side surface 141 and receives a reaction force toward the inclined guide rail 48. Cannot pass 28.
  As a result, fraud due to coin withdrawal is prevented.
[0048]
Next, the moving device 30 for the cancel piece 82 will be described.
As shown in FIG. 4, the moving device 30 includes an actuator 134 and a link mechanism 136.
The link mechanism 136 includes a slide plate 138 and a link 140.
The slide plate 138 is supported so as to be slidable in the orthogonal direction with respect to the inclined guide rail 48 along the bearing 142.
[0049]
  As shown in FIG.Large diameter bearing groove 122The first guide groove 144 and the second guide groove 146 are formed in parallel with each other, and the pin 148 on the end face of the cancel piece 82 is inserted into the second guide groove 146 corresponding to the small-diameter coin.
  As shown in FIG. 4, the actuator 134 includes a solenoid 150 fixed to the base 32, a plunger 152, and a return spring 154 of the plunger 152.
A link 140 is fixed to the tip of the plunger 152, and a slide plate 138 is fixed to the tip of the link 140.
[0050]
Therefore, when the solenoid 150 is not excited, the plunger 152 is protruded by the return spring 154, so that the slide plate 138 is pulled upward via the link 140.
Thereby, the cancel piece 82 is moved clockwise in FIG. 5 via the guide groove 146 and the pin 148, and the upper surface of the cancel piece 82 abuts against a stopper (not shown) of the base 32 and is indicated by a chain line.Cancel position 135 InRetained.
[0051]
As a result, even the genuine coin 14 is not supported by the front end 128 of the cancel piece 82 at the upper end side surface.
Accordingly, the coin 14 falls into the window 116, and the lower peripheral surface thereof is detached from the inclined guide rail 48 and falls at the canceling unit 20 due to its own weight.
[0052]
When the solenoid 150 is excited, the cancel piece 82 is rotated counterclockwise via the link mechanism 136, and the lower surface 156 of the slide plate 138 hits the tip of the adjustment screw (stop piece) 158 as shown in FIG. Then, it is moved to the non-cancellation position 133 that is a predetermined distance away from the inclined guide rail 48 and held.
In other words, it is held at the non-cancellation position 133 shown by the solid line in FIG.
[0053]
Therefore, the genuine coin 14 is guided toward the outlet 18 while the side surface of the upper end portion thereof is supported by the tip 128 of the cancel piece 82.
A small-diameter coin that is not allowed to be received falls on the window 116 due to its own weight and falls off the inclined guide rail 48 because its upper end side surface is not supported by the tip 128.
Large-diameter coins that are not allowed to be accepted cannot be rolled due to being jammed between the inclined guide rail 48 and the inclined guide 88.
[0054]
The moving device 30 only needs to have a function of moving the cancel piece 82 to the non-cancel position 133 and the cancel position 135.
When the cover 54 is pivoted further clockwise from the position shown in FIG. 5, the distal end portion 160 of the extruded piece 66 advances into the inclined passage 114 from the window 116, and pushes the coin 14 jammed there to tilt the guide rail. Drop from 48 and cancel.
The movement of the cover 54 is linked to the operation of a cancel lever (not shown) mounted on the game machine.
[0055]
Next, the small-diameter gauge position fine adjustment device 130 for the cancel piece 82 will be described.
As shown in FIG. 6, the small-diameter gauge position fine adjustment device 130 has a function of finely adjusting the distance between the inclined guide rail 48 and the lower edge 132 of the cancel piece 82.
That is, the position adjustment screw 158 that is screwed into the lower surface of the base 32 abuts on the lower surface 156 of the slide plate 138 so as to abut against the lower surface 156.
Therefore, the adjustment screw 158 is a stopper piece.
[0056]
The slide plate 138 is urged toward the adjustment screw 158 by a return spring 154 (see FIG. 7) integrally formed with the cancel piece 82, so that the cancel piece 82 does not move due to an allowable error.
  Therefore, the position of the lower edge 132 of the tip 128 of the cancel piece 82 is determined by the tip position of the adjustment screw 158.
In other words, by changing the screwing amount of the adjusting screw 158, the inclined guide rail 48 andLower edge 132Can be finely adjusted.
The adjustment screw 158 is locked by a lock nut (not shown).
[0057]
Next, the gauge position adjusting device 162 of the cancel piece 82 will be described.
This is used to change the position of the cancel piece 82 so as to conform to the position when the cancel piece 82 is largely adjusted by the mounting device 92. The gauge position adjusting device 162 is shown in FIG.Large diameter bearing groove 122 And small diameter bearing groove 124 It is.
[0058]
That is, the pivot 126 is inserted into the large-diameter bearing groove 122, the position of the slide plate 138 is changed by the adjusting screw 158, and the cancel piece 82 is set at a position that matches the new coin size.
When the coin size is one type, only the small diameter bearing groove 124 or the large diameter bearing groove 122 may be used.
When a large-diameter coin and a small-diameter coin are selected and used, it is preferable to mount the small-diameter bearing groove 124 and the large-diameter bearing groove 122 as the gauge position adjusting device 162.
[0059]
Next, the detection sensor for the coin 14 will be described with reference to FIGS.
The detection sensors include a first coin sensor 164 and a second coin sensor 166.
The first coin sensor 164 and the second coin sensor 166 are fixed to a bracket 170 fixed by a one-touch fixing means (not shown) to a stay 168 extending from the end face on the outlet 18 side of the gauge plate 80 along the inclined guide rail 48. ing.
  That is, the first coin sensor 164 is disposed immediately downstream of the gauge device 16 in the moving direction of the coin 14, and the second coin sensor 166 is disposed downstream thereof.
  First 1 Coin sensor 164 And second 2 Coin sensor 166 IsA pair of arms is a photoelectric type in which the light projecting unit and the light receiving unit are opposed to each other with the inclined passage 114 interposed therebetween.
[0060]
First 1 Coin sensor 164 And second 2 Coin sensor 166 IsWhen the coin 14 rolls on the inclined passage 114, the coin 14 is detected by detecting that the upper end of the coin 14 blocks the optical axis.
  First 1 Coin sensor 164 And second 2 Coin sensor 166 IsAs is apparent from the above structure, the gauge plate 80 is integrated and adjusted together.
[0061]
  With this configuration, the gauge plate 80 is adjusted along the straight line L. Therefore, when the coin size is changed,First 1 Coin sensor 164 And second 2 Coin sensor 166 IsWhile approaching or leaving the inclined guide rail 48, it also approaches or leaves the vertical guide rail 45.
  As a result, even if the coin size changes, the coin 14 crosses the optical axis at the same timing.1st coin sensor 164 And second 2 Coin sensor 166 The position ofThere is no need to individually adjust the position or change the detection timing.
[0062]
  Also,1st coin sensor 164 ofBased on the detection signal, the solenoid 150 is excited via the cancel circuit 169.
  That is, as shown in FIG.1st coin sensor 164 ofThe solenoid 150 is demagnetized after a predetermined time TD from the detection signal T1, thereby moving the cancel piece 82 to the cancel position 135 and causing the stopper 28 to protrude into the inclined passage 114.
The delay time TD is a time during which the stopper 28 can enter the upper fan-shaped space when the coin 14 rolls continuously.
[0063]
Next, the guide 172 of the coin 14 discharged from the outlet 18 will be described.
The guide 172 is detachably attached to the end surface of the base 32 by one-touch fixing means.
When the guide 172 is mounted, the lower end of the guide 172 from which the coin 14 falls substantially becomes the exit.
[0064]
The guide 172 has a groove shape in which a tall guide wall 174 is formed on the inclined lower surface side of the coin, and the opposite side forms a wall 176 lower than the guide wall 174, and the lower surface is gently curved forward. ing.
By lowering the wall 176, the coin 14 is prevented from being clogged with the guide 172.
[0065]
Next, the operation of this embodiment will be described.
The cancel piece 82 is attached so as to be adapted to the small-diameter coin as shown in FIG.
That is, the first holding pin 96 is inserted into the first fitting hole 100, and the second holding pin 98 is inserted into the second fitting hole 102.
First, a case where the coin 14 is accepted and the genuine coin 14 is inserted into the insertion slot 12 will be described.
[0066]
That is, the solenoid 150 is excited and the plunger 152 is pulled down, and the slide plate 138 is moved in the same direction via the link 140 and stopped at the top of the adjustment screw 158.
The tip 128 of the cancel piece 82 has been moved to a non-cancel position 133 that guides the side surface of the upper end of the genuine coin 14 as shown in FIG.
The stopper 28 is located at a non-cancel position 145 that is out of the inclined passage 114.
[0067]
The coin 14 falls while being guided by the vertical surface 38, the cover vertical surface 56, the vertical guide rail 45, and the vertical guide 62.
The coin 14 is then guided by the curved surface 40 and the cover curved surface 58 and tilted by about 70 degrees (see FIG. 5) with respect to the horizontal line, and then rolls on the arcuate guide rail 46 and the inclined guide rail 48 to the outlet 18 After reaching, it is guided by a guide 172 and supplied to a hopper (not shown).
[0068]
In other words, in the vertical portion passage 110 and the curved portion passage 112, the upper and lower end portions of the coin 14 are in contact with the vertical surface 38 and the curved surface 40, and the central portion is close to the cover curved surface 58.
In other words, the central portion of the coin 14 is separated from the base 32.
However, since the diameter portion of the coin 14 is located on the second guide surface 74 side, the upper and lower ends do not contact the vertical surface 38 and the curved surface 40, and the distance between the first guide surface 72 and the vertical surface 38 is The thickness is slightly larger than the thickness of the coin 14.
[0069]
As a result, the coin 14 falls smoothly without vibrating.
Further, when rolling on the inclined guide rail 48, the lower end side surface of the coin 14 is guided by the inclined surface 42, and the upper end side surface is supported by the tip 128 of the cancel piece 82, so that it does not fall from the inclined guide rail 48.
The coin 14 that has passed through the gauge device 16 is detected by the first coin sensor 164 and the second coin sensor 166, then rolls from the outlet 18 to the guide 172, and falls from its end to a hopper (not shown).
[0070]
  Next, a case where a coin 14 larger in diameter than a genuine coin is inserted will be described.
  Vertical passage 110The large-diameter coin 14 that has passed through the curved portion passage 112 cannot be rolled by being sandwiched between the inclined guide rail 48 and the inclined guide 88, that is, is stopped in the inclined passage 114.
  In this case, by pivoting the cover 54 and the extruded piece 66, the coin 14 is pushed laterally at the lower end portion 160 of the extruded piece 66, removed from the inclined guide rail 48, and dropped to cancel.
[0071]
In the case of the small-diameter coin 14 that is smaller than the allowable allowable range, when the inclined guide rail 48 is rolled, the upper end side surface is not supported by the tip 128 of the cancel piece 82 and falls into the window 116.
As a result, the coin 14 falls off the inclined guide rail 48 and is canceled.
[0072]
Further, when the coin 14 is not received, the solenoid 150 is demagnetized, the plunger 152, the link 140, and the slide plate 138 are pushed up by the return spring 154, and the cancel piece 82 becomes the cancel position 135 in FIG.
Furthermore, the stopper 28 protrudes into the inclined passage 114 and is located at the cancel position 143 as shown in FIG.
Since the genuine coin 14 inserted in this state is not guided by the tip end 128 of the cancel piece 82 on the side surface of the upper end portion thereof, the genuine coin 14 falls to the window 116 and falls from the inclined guide rail 48 to be canceled.
[0073]
When the coin 14 does not fall from the inclined guide rail 48, the stopper 28 protruding into the inclined passage 114 stops the coin 14 and drops it from the inclined guide rail 48.
When the coin 14 collides with the stopper 28, the upward arc surface abuts against the downward surface 139 of the stopper 28, so that the coin 14 is pushed downward by the reaction force and cannot pass over the stopper 28.
[0074]
Further, since the downward surface 139 that contacts the coin 14 of the stopper 28 has an inclination toward the side of the inclined guide rail 48, the force pushed sideways from the inclined passage 114 when the coin 14 abuts. Can be canceled more reliably.
In addition, since the tip of the stopper 28 is formed in a tapered shape, the coin 14 can be canceled even if it protrudes into the inclined passage 114 at a critical timing that is likely to contact the peripheral surface of the coin 14. Can do.
